Spamel OP1-W01-A-M smart switch push button OP1 with 2 normally closed channels, 1 normally open channel and hammer release

The Spamel OP1-W01-A-M smart switch push button OP1 is a compact electromechanical device designed for control and signaling tasks in electrical panels and industrial installations. It combines two normally closed (NC) channels and one normally open (NO) channel in a single push-button assembly, and features an integrated hammer release mechanism for manual or safety-triggered reset. The unit is intended for applications where mixed NC/NO switching is required to implement safety interlocks, alarm circuits, or control logic.

Advantages

The push-button design provides clear tactile actuation and reliable contact switching for both NC and NO circuits. Having two normally closed channels alongside a normally open channel allows flexible wiring schemes for monitoring and control without additional modules. The built-in hammer release mechanism enables a quick manual disengagement or reset in emergency or maintenance situations, simplifying operation and reducing downtime. The compact form factor fits standard panel cutouts and supports straightforward installation in industrial control cabinets.

Suitable for

• Control panels and switchboards requiring mixed NC/NO contacts
• Alarm and signaling circuits where fail-safe NC channels are needed
• Industrial machinery control and interlock systems
• Maintenance or emergency reset points using hammer release actuation

Key specifications

• Contact configuration: two normally closed channels and one normally open channel
• Actuation type: push-button with integrated hammer release mechanism
• Intended mounting: panel-mount suitable for electrical control cabinets
• Application area: control, signaling, safety interlocks and alarm circuits

How to use

Mount the switch in a compatible panel cutout and connect wiring according to the control scheme, assigning the normally closed and normally open contacts to the respective circuit functions. Use the NC contacts for circuits that must default to a closed state for safety or monitoring, and the NO contact for circuits that should close only when the button is actuated. The hammer release can be used to manually reset or release the mechanism when required; follow standard electrical safety procedures and de-energize circuits before installation or maintenance.

Usage recommendations

Verify compatibility with the panel cutout dimensions and the electrical ratings of the connected circuits before installation. Use the NC channels for fail-safe monitoring and the NO channel for activation functions. Perform periodic inspections of contacts and the hammer release mechanism in environments with dust, moisture, or vibration to ensure reliable operation.
